Sederhanakan bentuk aljabar berikut :
a. (x+4)^2+(x+4)^2
b. (5-y)^2+(5y-1)^2
c. [1/2x+2]^2+[1/2x-2]^2

Tolong pakai caranya dan jangan ngasal... Thanks :)

Answer 1

Jawaban soal a
= (x+4)²+(x+4)²
= x² + 4² + x² + 4²
= 2x² + 8²

jawabn soal b
= (5-y)²+(5y-1)²
= 5² -y² + 5y² -1²
= 5y² + 25-1
= 5y² + 24

jawabn soal c
= [1/2x+2]^2+[1/2x-2]^2
= 1/2x² + 2² + 1/2x² - 2²
= x²
